Restore Your Truck’s Flawless Performance
Is your Sierra Denali, Silverado, or Camaro experiencing frustrating transmission issues? Hesitation, harsh shifts, or a sudden check engine light can ruin the driving experience of an otherwise incredible vehicle. This isn’t just an inconvenience; it’s a sign that the brain of your transmission may be failing. Our VIN-programmed Transmission Control Module (TCM) is the definitive, reliable solution to get your truck back to operating with the smooth precision you expect.
Common Symptoms & Your Solution
A faulty TCM can cause a cascade of problems that can be easily misdiagnosed. If you’re experiencing any of the following, this module is your answer:
- Erratic or harsh shifting between gears
- Delayed engagement when shifting into Drive or Reverse
- The vehicle entering “limp mode” with reduced power
- Check Engine Light with transmission-related Diagnostic Trouble Codes (DTCs) such as P0700, U0101, or P0751
- Poor fuel economy due to inefficient shifting
Instead of risking a costly and time-consuming trip to the dealership, this module arrives ready for installation.

Expert Insight: The Brains Behind the Brawn
The 10-speed automatic transmission in your GM truck is a marvel of engineering, but its complexity means it relies heavily on its electronic controller—the TCM. When it fails, the entire system is compromised.

Our solution bypasses that entire headache. By pre-programming the 2019-2020 Sierra Denali 1500 Transmission Control Module to your specific VIN, we provide a component that is electronically identical to the original, ready to restore the intelligent shifting and robust performance your premium truck was built for.
